4 Claims.

This invention relates to oil burning equipment andmy present improvements are directed to means for the simultaneous control of air in its admission to an air register through forward and 5 side inlets thereof. v

Particularly my invention is intended for employment where the fire room of a marine oil burning vessel is divided by a bulkhead into a boiler compartment and an operators compart- 10 ment, as instanced in my co-pending application Serial No. 88,736, filed July 3, 1936. Y The surrounding wall of the air register ineluded in` this new oil burning equipment has certain novel structural features which enable it "i5 to possess side air admission control means that are co-operative with other control means, also of novel character, for rearwardly directed air streams that enter through the front of the o register. f *o Single operating means, which extend from the boiler compartment, through the bulkhead, into the operators compartment, 'are employed to actuate mechanism which Acontrols the air admission means of the register wall, and inter- 25 connecting means, intermediate said mechanism and the air control means through the register front, serves to actuate the latter air control means.

Other features and advantages of my invenl moreparticularly illustrate the actuating mechanism for the means controlling the passage of air through the front inlet of the register.

45 In said views let I indicate aboiler plate having a furnace opening with a Venturi ring 2 therein and an air register extending forwardly therefrom. Saidregister is composed of the segmental doors 3, eight being here shown in Fig. 4, each 50 secured to and carried by a sleeve I that is rov tatable about van exteriorly disposed, fixed bolt 5, these bolts being equi-spaced apart and secured at their opposite ends respectively in the rearward ring 6 and theforwardring 1. It will be 55 noted that for convenient assembly the bolts 5 Fig. 5 is a detail side view, partly in section, to`

(Cl. s-1.5)

abut against the flange 8 of venturi 2, and a reduced terminal of said bolts is extended through ring 6 and secured by nuts 9.

Secured to each of the doors 3 is an air directing vane I0 having a curved inner surface adapt- I ed to impart spiral motion to air currents flowing thereover. Also each door 3 has secured to its outer surface a curved plate II that covers the bolt .5, its purpose being to prevent air currents from retardation by striking exposed bolts. l0

It is my purpose to provide means for opening, closing and regulating the said series of dors in unison, as will appear hereinafter in the description of the control means.

The sleeves 4 are extended forwardly beyond 15 the ring 'I and are there mounted on stub shafts I2 and I2a which are secured to said ring, said sleeves, near their forward end, having each a centering arm I3 upon which is mounted a roller I4 that engages a slot I5 in a disk I6, said disk being rotatably mounted on a hollow casting I1. Said casting I1 surrounds the usual burner tube casing I8, that itself contains the burner tube I9, which latter is axially adjustable.

A flame cone is shown as attached to the 25 casing I8. A telescopic shroud, indicated at 2l, may or may not be employed with said flame cone.

A frame member 22 extended from casting I1 and secured to the stub shafts I2, serves as a base for the bellows 23 (disclosed in my said applica'- 30 tion Serial No. 88,736) which extends between said member and bulkhead 24.

Also the casting I1 forms a bearing for an operating shaft 25 which extends through the bulkhead, being provided With a stuffing box 26, to 35 prevent leakage. Shaft 25 carries forwardly of the bulkhead. a crank 21 having an operating handle 21. Said crank 21 is provided with an apertured boss 28 in which is fitted abolt 29 Whose headed end engages an arcuate slot 30 40 formed in a bracket 3| that is mounted on shaft 25 and held in fixed relation with the bulkhead by means of a bolt 32. The arcuate slot 30 enables the crank to rotate shaft 25 to a desired set postion and the Wing nut 33 on bolt 29 is 45 then tightened to clamp the crank in such set position.

The rearward end of shaft 25 is provided with an eccentric 34 that engages a U-shaped abutment 35 carried by the disk I6, by which means 50 a partial rotation of shaft 25 will impart a corresponding movement to disk I6, and this-movement in turn will be transmitted, through' arms I3 and sleeves 4 to the doors 3 and vanes I0.

It is in this manner that air may be admitted.' 55

in desired volume. into the register through its surrounding wall.

The register iront is composed of a series of vanes or shutter-like members I8, each being carried by a rod 31 havingone end 3B pivoted in the ring 1, its other end being pivoted in a bearing formed in the wall 39 of a disk-like member 4I that 1s secured about the casting i1. Within the circumference of wall 39 the rods 31 are angled, as shown at 4I, and are entered within openings provided therefor in pistons 42, said pistons respectively being operable in cylindrical pockets formed for their reception in a circular plate 43 that is rotatable in bearings about the casting i1. A link 44 connects plate 43 with disk I6 and serves to communicate motion from disk It to said plate 43. Said link 44 carries a stud 4I that is engaged by guide members 4t on plate 43,

the outer end or said link having a slot 41 that engages a pin 4I carried by the disk IS, a stationary pin 49, which serves as a fulcrum for link 44, engaging in a slot 50 formedin disk i4, to permit free movement of said disk.

Ii'rom theoregoing description it will appear that the rotating motion of disk I6 is transmitted through link 44 to member 43, to operate the pistons 42 and thus the vanes I6, said operation imparting to said vanes a degree oi' opening commensurate with the degree of opening imparted to side doors 3, so that the ow of air through the register front occurs simultaneously with, and in proportion to the inflow of vaix' through the register wall.

In the slight reciprocating motion of pistons 42 a cushion of air wouldl occur in the cylindrical pockets of plate 43, and to obviatesuch occurrencev a vent 5| may be formed in the base of said pockets.

Variations within the spirit and scope of my invention are equally comprehended by the toregoing disclosure.

I claimz- 1. An air register for use with furnaces having a front wall with an opening therethrough, said register having a front inlet that admits rearwardly directed air toward said opening, a sexies of vanes in said front inlet to regulate air admission, rotatable rods carrying said vanes and having angled ends, a central hollow member, a disk rotatably mounted on said member, operatmg means to rotate said disk, a plate rotatably mounted on said member and having radial pockets therein, pistons operable in said pockets, the angled ends of said rods engaging said pistons, and means operatively connecting said disk and said rotatable plate to transmit movement from said disk to said plate for the operation of said pistons and vanes.'

2. The subject matter oi claim 1 in which the movement transmitting means comprises a link pivotally connected to said disk and to said rotatable plate, a stud carried by said link, and,

xed guide members on said rotatable plate with which said stud is engaged.

3. An air register for use with furnaces having a front wall with an opening therethrough, said register including a series of equi-spaced bolts extending out from the periphery of said opening, sleeves rotatable on said bolts, segmental doors carried by said sleeves and curved air stream directing vanes carried by Said doors, arms extending !rom said sleeves, a disk freely engaged by the ends of said arms, a support 'on which said disk is rotatively supported, and operating means for rotating said disk.

4. The subject matter of claim 3, wherein said sleeves and air stream directing vanes are connected to opposite faces of said doors and said bolts are covered by plates for directing the air past the bolts.
